Self-Defense and the Israeli Wall Advisory Opinion: An Ipse Dixit from the ICJ?

In October 2003, the Israeli permanent representative addressed the United Nations General Assembly on why Israel felt compelled to build a lengthy barrier spanning hundreds of kilometers across certain areas of the occupied West Bank of the Jordan River. Among other things, Ambassador Dan Gillernian stated: [A] security fence has proven itself to be one of the most effective non-violent methods lor preventing terrorism in the heart of civilian areas. The fence is a measure wholly consistent with the right of States to self-defence enshrined in Article 51 of the Charter. International law and Security Council resolutions, including resolutions 1368 (2001) and 1373 (2001), have clearly recognized the right of States to use force in self-defence against terrorist attacks, and therefore surely recognize the right to use non-forcible measures to that end.
